portion of the vborewill form a seat foi vthe leather washer 23, which will make a tight joint between the bore for the cable andthe enlarged portion of 'said bore. A steel washer 21 is maintained against the leather `washer by an equalizing spring 25 mounted on the cable 13 between theshoulder 10 and The upper portionvof the sleeve 22 is eX- teriorly4 reduced in diameter, and the upper end thereof fits snugly into the central bore 'of a cap 2G threaded into the upper end of the bore section 8, the cap 26 being locked to the shell by a setscr'ew 27 or any otherA suitable means. The lower part of they bore washer 28 resting against 7the bottom formed bythe enlargement of the bore. A steel washer 29 is positioned between the spongy washer 2S and packing rings 30. This ar- 'rangement of the packing rings, spongyA washer, and the metallic washer forms a stul'liiig bo for the adj Listing sleeve 22within the cap 26. The packing rings are selfadjustable under the action of an adjusting spring 31 positioned on the reduced portion of the sleeve 22. A washer' is' preferably provided between. the lendl of the spring and the use of the contrivance as a swivel socket. This arrangement prevents the abrasive material present in the well from working its way between the-adjusting sleeve and the fao cap 26'. Although the sleeve 22 is babbitted to the cable 13, a passage may be left Where the sand may work its way between the sleeve and the cable, and to prevent this a leather washer 32 is mountedon the cable which abats against a collar 3l formed on the cable. l 1

. The guide sleeve 22 and the cable head 12 are made to work in a lubricant, which is introduced into the bore sections 6 and 8 through the bore section 7 by providingay threaded aperture 35 leading from the side of the shell into said bore section and normally closed by a plugSG. By removing-the plug a grease cup can be inverted and the lubricant forced through the bore section 7 into the lower and upper bore sections 6 and 8 respectively. The threaded aperture 35 is necessary to remove the cable head `12 and "the guide sleeve 22. The guide sleeve 22 and lthe cable head 12 are provided on their lat'- eral surfaces with helical grooves 37 to feed thc grease along the surface of the bore secgularly, as sho-wn at 39, 'whereby the saine in the cap 26 is enlarged .to receive a sp'ongy"I can be handled with a suitable wrench.

The connection of the cap 264 with the `shell 5, as shown in Fig. 2, is only used when the diameter of the. well does not perlnit .also used for ysevering the cable v13 when countersinking ofthe cap 26', as shown `in Fig. 3. This is due to the fact that in 'relatively sinall drill holes the upper end of the shell 5 must be reducedsuficiently to facilitate the extracting of tools that may be made necessary by a riipture of the cable.

In Fig. l a further modification `of the I shell is shown, by making .the lower threaded end ofthe bore 38 cylindrical, for the reason that the cone-shaped end will greatly reduce the diameter of the bore section 6,

which is not desirable; and to obviate this,

the boreis made cylindrical and an extension 40 is inserted between the cable socket and .the tools to be connected thereto. It is understood'that the extension 40 is for use only in small sockets for small sized drill holes. v.

To fasten the socket to the cable, care must the packing ring to reduce friction during.lib-:taken t0 Put u Parts 0n the Qfkble, in the Before the ,babbitt cools, the washer 14 is inserted into position. The socket is then suspended on the cable 13 so that the head` will seat itself against the washer 11. The bore of this washer 11 is preferably made a little smaller than the diameter of the bore order shown in. the drawings,,from-.the tOp--I' to the bottom; then the end-of the cable 13' section 7, so that the washer can be easily removed by a iod fitting snugly into the bore section 7 The adjustable plug 18 can then be screwed into position and the compression of the cushion spring 15 thereby .adj usted and the plug locked to the shell by the slet screw 20. This will permit the head 4as to maintain said washer against the cap.

insa-sia tom a tight bottom `for the sleeve bore. Preferably grooves 41 are provided `within the bore of the sleeve so as togive.

a better gripv tol the babbitt. The leather fwasher32 is'then forced against the topl of vthe cap and the end of Athe sleeve, and the conical spring 33 is then tied to the cable so of the sleeve as stated. If it is desired now to change the swivel socket to a solid socket for a short period of time, the set screw 21l is used, ,whereby the head 12 is locked tothe shell; but whenthe contrivance is to be used for a solid socket fora long period of time, the

- quently, wear.

adjustable plugvl8 is moved against the head 12, as described, and in addition .the set screw 21'n1ayl also be used.

It will be ,noticed that all the moving-parts of my socketsare completely cushioned' by springs,.preventing hammering and, conse# Further, all the moving parts are submerged in a lubricant and .abrasive material is prevented from enter ing and injuring the moving parts. It' sim pliiiesand reduces the cost of operation, in

that one socket answers the purpose of two.

Further, a great saving in time is .secured when a changelfrom a swivelto a solid socket, or vice versa, 1s necessary.
